Bump to version 1.1.0. The cross-compile patch for 1.0.29 does not
appear to be needed, so not carrying it forward for 1.1.0. Mask all
architectures until deemed 'stable' by gentoo-sound team.

TODO: Version 1.1.0 does introduce the DSP Topology API. This is enabled
by default, though there is a configure flag to disable it. There are
kernel configuration and ABI version considerations to account for in
any future "topology" USE flag handlers-- I haven't sufficient expertise
to "do it right" at this time, or I would do so.
